Pyplot animation example.

The method shown here is only for very simple, low-performance
use.  For more demanding applications, look at the animation
module and the examples that use it.

import matplotlib.pyplot as plt
import numpy as np

x = np.arange(6)
y = np.arange(5)
z = x * y[:,np.newaxis]

for i in xrange(5):
    if i==0:
        p = plt.imshow(z)
        fig = plt.gcf()
        plt.clim()   # clamp the color limits
        plt.title("Boring slide show")
        z = z + 2

    print("step", i)
